As i say again, you show me where there was intention by the USA to kill any segment of the population?
I'm only a layman, but I'd imagine that the dropping of tens of thousands of lbs of ordnance into a city centre, would - at the very least - give an indication of them not giving a monkey's either way.
As far as Iran itself is concerned, I'm not sure that an Israeli air-strike would be helpful. It's likely to achieve sod-all anyway, and could only stoke things up unnecessarily.
Also - and we're re-treading old ground here - your argument about "their" country being bombarded, legitimising Israel's reponses in Gaza and Lebanon, really only holds water if you believe that the disputed territory really is "their" country.
Israel is viewed as an occupying force in large parts of Palestine by many Arabs - and others (including the UN). This is something that Israel doesn't even dispute, so is it any wonder that those who have been dispossesed, have chosen to take up arms?
As for Ahmedinejad, his posturing is clearly rhetoric, and those who hide behind the "He would drive the jews into the sea" argument, are kidding themselves - and everyone else - on. Iran's standing army massively outnumbers that of Israel, and if he was serious, he could have played out his fantasy a long time ago.......if he was serious.
